I miss running them. I would do it now but the queues are worse than PVP. If they changed the reward for the weekly from Ironworks upgrade items to Esoteric upgrade items, it would probably get people back in there. Unfortunately they're probably saving that for the Ark Void, so if they don't come up with something else, it will remain pretty dead. People still run old Coil and EX primals for glamour, but they have added appeal in that EX primals also drop ponies, and primals and Coil both count towards the tank mounts.

Also I could be wrong but I don't think you can run any of the towers unsynced, even if you go in a with a full 24 man alliance. So, that might not be an easy solution as some people are suggesting.
